Weeds are the noxious plants that stunt growth and yield of many crops. This study
recorded the community composition of weeds in maize crops grown at District Khairpur,
Sindh, Pakistan. The weeds were collected from the maize crop at three different localities
using the quadrat method (60 quadrats/site). The species were identified and herbarium
samples were preserved in Herbarium, Shah Abdul Latif University, Khairpur, Sindh
Pakistan, for future reference. The species community composition, habit, and life span
were determined. The study confirmed 35 weed species belonging to 14 plant families. The
weed community was dominated by the plant families Poaceae (8 spp.), Amaranthaceae (7
spp.), and Aizoaceae (3 spp.). The most frequent species with relatively higher densities
include Digera muricata (Amaranthaceae), Trianthema portulacastrum (Aizoaceae), and
Corchorus olitorius (Malvaceae). The weed community was dominated by annual herbs. The
community composition among the study sites was highly comparable. The study found a
lack of weed management practices across the sites.
